Editing Warhammer 40,000/7th Edition Tactics/Cult Mechanicus (section)

===Ranged Weapons===
*'''Heavy Arc Rifle:''' It's a 36" 2 shot Haywire gun with S6. Comes default on Breachers. Use it to pop open any vehicles giving you grief or to reveal the tasty transported center.
*'''Cognis Flamer:''' Sounds redundant, right?  After all, template weapons already deliver d3 automatic hits on overwatch, so what's the deal?  This gives you 3 instant hits on overwatch, every time.  Goodbye, mobs.
*'''Macrostubber:''' S4, but shoots 5 shots even though it's considered a Pistol. Could be fun against hordes. But since their premier user is the Tech Priest Dominus with his BS5, it might even kill a MEQ.
*'''[[Volkite Weaponry]]:''' In a huge, blatant nod to Forge World's Horus Heresy line, we can now also use the awesome Volkite weaponry used in the Horus Heresy. And since 40k has (marginally) fewer MEQs running around, this might be their place to shine. They come stock with the Deflagrate rule, which means that for every unsaved wound the gun causes, the unit takes another identical hit. New hits do not themselves cause new hits.
**''' Volkite Blaster:''' It's a S6 AP5 three shots, 24" blunderbuss.
*'''Phosphor Weaponry:''' All Phosphor weapons come stock with the Luminagen rule. This means that, if the gun scored at least one wound/glance/pen, all squads re-roll failed charge distances against the affected unit, and their cover save is also lowered by 1. Just as it was in the Skitarii book, the Luminagen rule doesn't care if your allies are Come The Apocalypse, they can use it, too.
**'''Phosphor Serpenta:''' It's an 18" Assault 1 Heavy Bolter. Honestly, unless you're shooting at Orks outside KFF range, you won't be killing anything with this.
*** Alternate Opinion: The Dominus's Phosphor Serpenta has one advantage, and that is applying Luminagen at a longer range than a Phosphor Blast Pistol. By that, it has some support potential for long-ranged units, like Skitarii Rangers, with which you won't typically be planing to get into pistol range anyway.
**'''Phosphor Blaster:''' As above, but it's now 24" and Rapid Fire. 
**'''Heavy Phosphor Blaster:''' Now we're talking. Three shots, Strength 6, AP3 and 36" range. It's an awesome MEQ killer and a unit of Castelans fully loaded with them might even glance transports to death.
*'''Plasma Culverin:''' 24", 2 shot Plasma Cannon. Yes it still Gets Hot and small blasts are usually pretty meh, but when you can have entire units full of these things, they get scary.
**''' Plasma O'death:''' In a normal squad this is 6 plasma blasts! If you aim for an area where the enemy is packed (several units) you can with some luck see the blasts scatter and hit more than the unit you were aiming for. If you use the re-roll canticle you can reroll the bad scatters and hold on to the other ones. Use the phosphorous blaster before for some anti-cover shenaigans. Add in a Haemotrope Reactor and watch vast swathes of the enemy vanish, note the new rules errata states the ability to re-roll 1's to hit allows re-rolls to blast weapons gets hot- use the Benediction of Omniscience to prevent the servitors from suffering wounds.
*'''Heavy Grav-Cannon:''' 30", Salvo 4/6. Just like the Space Marine Grav Cannon, the Salvo part is irrelevant and the gun is pretty much Assault 6 in all but name. Blows holes into MEQs and TEQs and has enough shots to squash any vehicle regardless of AV, but is utterly useless against hordes and Daemons.
*'''Gamma Pistol:''' A nice toy your Datasmiths get to play with, it's a S6 AP2 pistol with Armourbane. In practice, it's better than a Meltagun between 6 and 12" and worse than a Meltagun at lower ranges.
*'''Torsion Cannon:''' The other gun that the Breachers can take. One shot at Strength 8 ap 1 with a unique rule that allows you to take off D3 wounds/Hull points for an unsaved wound or penetrating hit, though not for a glancing hit. However, if you use the Holy Requisitioner formation, they might be useful, since you could deep strike in a way that might allow you to target the side/rear armor values of big things like Imperial Knights and Lords of Skulls. ''Note all the subjunctives in that sentence, though.''
*'''Incendine Combustor:''' Stock gun on the Kastelans and proof that sometimes (only sometimes) GeeDubs does consider what an army needs and then actually gives it to them. Before the Castelans came out, the Mechanicus was in desperate need of flamers. Now you have Torrent Flamers to toss into blobs! It isn't an amazing gun by a long shot, but considering that every single Castelan has one at no additional cost...
*'''Eradication Ray:''' Oh look. It's another bloody reverse variant of the Conversion Beamer! This one is actually pretty good. Between 0 and 12" it's a single shot S8 AP1 haymaker, because fuck those Paladins in particular, and between 12 and 24" it's a S6 AP3 blast, because fuck MEQs in general. The only downside to using it is that you have to pay 15 points ''and'' give up the equally cool Volkite Blaster to get it.
